This study was carried out in two stages; first, a well-structured questionnaire was used to collect data on socio-demographic variables and parental fear. Second, clinical examination was performed to measure dental caries according to the World Health Organization (WHO) diagnostic criteria and to record the dental services utilized.

Likewise, a higher percentage of children had fillings in their primary dentition (14.1%) than in their permanent dentition (5.1%). 6-8 yearss age, of 6-8 years, significantly impacted dental caries prevalence and service utilization. Being in private schools significantly reduced dental caries in both types of dentitions (DMFT: Regression Coefficient (B) =-0.160, P-value (P) = 0.032), (deft: B=-0.459, P = 0.007). Children whose fathers had a higher educational level demonstrated lower dental caries scores in both dentitions (DMFT: B=-0.300, P = 0.023), (deft: B= -0.429, P = 0.035).
